In the house perfectly, no use for the car.

I use the magnetic charging cable for my Xperia Z3. The magnet is strong enough to use the phone while charging and it will continue to charge easily. Even if the phone is dropped, the charging process does not stop. The loading speed I find very good. I own the docking station from Sony and have not noticed any differences.

Now to the problem:
I was planning to use the cable car to also here not having to constantly open the cap.
At first I was excited, but then I noticed that the charge will stop after a few minutes drive. I suspect that by the vibration while driving slip the contacts, so that the charging process terminates. Optically it does not change its position while it's all like when functioning charging.
Now, when I sit up the cable again while driving, the whole thing repeated - after a few minutes is again closing.

So unfortunately, the cable fails the function that I had wished for. I will still continue to use it, because it is basically very good.
